Channel closing in strong-field photoemission from tip arrays
Leon Brückner, Jonas Heimerl, Constantin Nauk +1
Ultrafast photoemission is a promising avenue for the development of petahertz electronics. For such devices, identifying the precise emission mechanism and quantifying the local f…
Spatial and energetic correlations of ultrashort two electron pulses
Stefan Meier, Jonas Heimerl, Felix López Hoffmann +3
When two electrons are emitted from a metallic needle tip into a nanometric volume on femtosecond timescales, strong Coulomb correlations arise. While longitudinal correlations, ma…
Attosecond physics in optical near fields
Jonas Heimerl, Stefan Meier, Anne Herzig +8
Attosecond science, the electron control by the field of ultrashort laser pulses, is maturing into lightfield-driven electronics, called petahertz electronics. Based on optical fie…
Driving electrons at needle tips strongly with quantum light
Jonas Heimerl, Andrei Rasputnyi, Jonathan Pölloth +3
Attosecond science relies on driving electrons after photoemission with the strong optical field of a laser pulse, representing an intense classical coherent state of light. Bright…
Multi-photon electron emission with non-classical light
Jonas Heimerl, Alexander Mikhaylov, Stefan Meier +4
Photon number distributions from classical and non-classical light sources have been studied extensively, yet their impact on photoemission processes is largely unexplored. In this…
Deep Learning-Based Spatiotemporal Multi-Event Reconstruction for Delay Line Detectors
Marco Knipfer, Stefan Meier, Jonas Heimerl +2
Accurate observation of two or more particles within a very narrow time window has always been a challenge in modern physics. It creates the possibility of correlation experiments,…
Few-electron correlations after ultrafast photoemission from nanometric needle tips
Stefan Meier, Jonas Heimerl, Peter Hommelhoff
Free electrons are essential in such diverse applications as electron microscopes, accelerators, and photo-emission spectroscopy. Often, space charge effects of many electrons are…
